Method of rendering textiles flame retardant and the product

ABSTRACT

Normally flammable textile materials are rendered flame retardent by the intimate association therewith of a flame retarding amount of a composition comprising a phosphorus containing N-hydroxymethyl amide and tetrakis(hydroxymethyl) phosphonium chloride.



1. A PROCESS FOR RENDERING NORMALLY FLAMMABLE TEXTILE MATERIALS FLAME RETARDANT WHICH COMPRISES INTIMATELY MIXING SAID TEXTILE MATERIALS WITH A FLAME RETARDANT AMOUNT OF A COMPOSITION COMPRISING A PHOSPHOROUS CONTANING N-HYDROXYMETHYL AMIDE AND TETRAKIS (HYDROXYMETHYL) PHOSPHONIUM CHLORIDE.
 2. The process of claim 1 wherein the mole ratio of N-hydroxymethyl amide to tetrakis (hydroxymethyl) phosphonium chloride is from about 1:1 to about 1:0.05.
 3. The process of claim 1 wherein said textile material is cotton.
 4. The process of claim 1 wherein said N-hydroxymethyl amide is
 5. The pocess of claim 1 wherein said N-hydroxymethyl amide is
 6. The process of claim 1 wherein said textile material is wool.
 7. The process of claim 1 wherein said textile material is a blend of polyeSter and cotton.
 8. Flame retardant textile material comprising normally flammable textile material and a flame retardant amount of a composition comprising a phosphorus containing N-hydroxymethyl amide and tetrakis (hydroxymethyl) phosphonium chloride.
